Alexander asked for volunteers, whom he would reward if they could climb the cliffs under the fortress. There were some 300 men who from previous sieges had gained experience in rock-climbing. Using tent pegs and strong flaxen lines, they climbed the cliff face at night, losing about 30 of their number during the ascent. In accordance with Alexander's orders, they signalled their success to the troops below by waving bits of linen, and Alexander sent a herald to tell the defenders that if they looked up, they would see that he had found his winged men. The defenders were so surprised and demoralized by this that they surrendered, even though they outnumbered the mountaineers by a hundred to one and Alexander's main force still had no way to reach the summit. The defenders had thought that the Rock was impregnable, and with one bold stroke Alexander showed them how wrong they were. The enemy's quick surrender validated Alexander's insightful use of psychological warfare.[1][2]

Alexander fell in love with Roxana on sight.[2] The Macedonians claimed that Roxana was "the loveliest woman they had seen in Asia, with the one exception of Darius' wife".[1]

From Sogdian Rock, Alexander advanced into Parsetakene which contained another supposedly impregnable craggy fortress known as the Rock of Chorienes,[3] but it was no match for Alexander and it was soon captured.[4][5] From there Alexander went to Bactra while he sent Craterus with a division of the Macedonian army to complete the pacification of Parsetakene. Alexander remained at Bactra, preparing for his expedition across the Hindu-Kush into India. It was while in Bactra that he married Roxana.[3]

The story of the siege of the Sogdian Rock is told in many histories, but it is based on the history written by the Greek historian Arrian of Nicomedia, in his Anabasis (section 4.18.4-19.6).[1] However P. J. Rhodes points out that "this version [of events] produces a very empty 328 and a very full early 327, so we should probably prefer the alternative tradition. In this second tradition instead of the Sogdian Rock and the Rock of Chorienes the same stratagems are used against the Rock of Arimazes and the Rock of Sisimithres in the summer of 328".[6]
